ModuleNotFoundError: No module named 'MySQLdb' in Flask-sqlalchemy – Phpmyadmin

I am just new in Flask, so I am trying to send data to the database using different tutorial source. I build simple blog type websites and my database server is http://localhost/phpmyadmin/. After I clicked on the submit button on contact.html. I got this error. So how can I fixed this error.

    return self.registry[key]
KeyError: 6528

During handling of the above exception, another exception occurred:

My code is here

from flask import Flask, render_template, request
from flask_sqlalchemy import SQLAlchemy
from datetime  import datetime

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://root:@localhost/blog'
db = SQLAlchemy(app)

class Contacts(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    email = db.Column(db.String(255), nullable=False)
    phone_number = db.Column(db.String(50), nullable=False)
    message = db.Column(db.String(120), nullable=False)
    date_created = db.Column(db.String(50), nullable=True )


@app.route('/contact/', methods=['GET','POST'])
def contact():
    if request.method == 'POST':
        name = request.form.get('name')
        email = request.form.get('email')
        phone_number = request.form.get('phone_number')
        message = request.form.get('message')
        entry = Contacts(name=name, email=email, phone_number=phone_number, message=message, date_created=datetime.now())
        db.session.add(entry)
        db.session.commit()
    return render_template('contact.html')

app.run(debug=True)

Does anyone knows, how I get this error ?

    Running command pip install pymysql and pip install mysqldbmodel help me to kicked this freaking(**) error.

    Edit:

    app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+pymysql://root:@localhost/blog'

    I find this solution at ImportError: No module named MySQLdb

    datetime.now: Does not return a String you need to convert it to String or change the type in the database to date like this

        date_created = db.Column(db.DateTime, nullable=True )

    I have used this and it worked very will with me

    from flask import Flask, render_template, request,redirect
from flask_sqlalchemy import SQLAlchemy
import sqlite3
from datetime import *

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///database1.db'
db = SQLAlchemy(app)

class Contacts(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    email = db.Column(db.String(255), nullable=False)
    phone_number = db.Column(db.String(50), nullable=False)
    message = db.Column(db.String(120), nullable=False)
    date_created = db.Column(db.DateTime, nullable=True )

db.create_all()

@app.route('/contact', methods=['GET','POST'])
def contact():
    if request.method == 'POST':
        name = request.form.get('name')
        email = request.form.get('email')
        phone_number = request.form.get('phone_number')
        message = request.form.get('message')

        entry = Contacts(name="name", email="email", phone_number="phone_number", message="message", date_created=datetime.now())

    try:
        db.session.add(entry)
        db.session.commit()
        db.session.close()
        return render_template('h.html')


    except:
        return "Error"

app.run(debug=True)

    You need to change the things i have changed like the render_template

    if it did not work please provide you github
